ALFRED EDMOND BURNOUF, OF BONNIFRES, FRANCE.

ROLLER-BEARlNG.

SPECIFICATION forming part of Letters Patent No. 643,890, dated February 20, 1900. Application filed August 8, 1899- fierial No. 726,586. (No model.)

To all whom it may concern.-

Be it known that I, ALFRED EDMOND BUR- NOUF, a citizen of the Republic of France, residing at Bonnieres, in the Department of Seine-et-Oise, France, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to roller-bearings; and the object thereof is to provide rollerbearings by the employment of which friction is materially decreased; and my invention consists in the construction and arrangement of parts, as hereinafter set forth in the specification, of which the accompanying drawings forms a part, in which like reference characters denote like parts in the several views, and in which- Figure 1 is an end view of a bearing constructed according to my invention; Fig. 2, a vertical longitudinal section of the outer portions thereof, the inner portions being shown unsectioned; Fig. 3, a transverse longitudinal section of the inner portions thereof, the outer portions being shown unsectioned 3 Fig. 4, an end view of a detail of construction, and Fig. 5 a vertical transverse section of the entire bearing.

Referring to the drawings, I have shown at A a transmission-shaft, which may represent an axle, trunnion, or other device. Mounted upon the shaft A are a pair of collars E, pro vided with radial grooves D, in which are mounted the end bearings C of rollers B,which are arranged longitudinally ofv the shaft A. The rollers B bear upon the shaft A and also upon a divided sleeve M, which is cylindrically formed, interiorly and exteriorly, of the form of two truncated conesF F, set base to base. The bases of the opposite segments of the cones F F are integrally connected by two crescent-shaped ribs G. The sleeve M is in one or two parts, and in the latter case theirjuncture O is at an angle With the shaft A. The ribs G terminate at their ends at the juncture of the two parts of the sleeve M.

The divided sleeve M bears exteriorly against two journal-box members J and H, of which the former is stationary, and the latter is vertically adjustable, and said journal-box shaft A may be passed. An annular piece of wood, metal, or other material is fitted into this opening as a packing.

Upon motion of the shaft A the rollers B are revolved, and the collars D, furthermore, are free to revolve upon the shaft A, forming an exceptionally-frictionless bearing. The journal-box member K may be adjusted so as to tighten the bearing, by means of the ribs G. As the cones F and F fit eXteriorly against conical surfaces interior of the journal-box members K L, the parts of the bearings will be always maintained in true alinement.

Having fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a bearing, a plurality of rollers suitably arranged and between which a shaft may be passed,a divided sleeve passed about said rollers and being cylindrically formed interiorly and of the form of two cones eXteriorly, a rib by means of which said cones are connected, said rib consisting of two members, each of which is crescent-shaped in form, and a pair of journal-box members in which said sleeve is mounted, and in connection with which sleeve one of said j ournal-box members operates to adjust said sleeve, substantially as shown and described.

2. A bearing of the class described, comprising a pair of journal-box members, one of which is adjustable and between which a shaft is passed, a pair of collars mounted on said shaft, a plurality of rollers journaled at their ends in said collars and arranged longitudinally of said shaft, a divided sleeve passed about said rollersand provided with a cylindrical inner surface and of the form of cones exteriorly, said cones being connected by a divided rib consisting of two parts, each of which is crescent-shaped in form, said cones operating in connection with the inner surfaces of said journal-box members, substantially as shown and described.

In testimony that I claim the-foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 25th day of July, 1899.

ALFRED EDMOND BURN OUF.
